1. SUPPLEMENTAL RESTRAINT SYSTEM
ªAIRBAGº
Airbag system wiring harness is routed near the
cruise control module and cruise control command
switch.
CAUTION:
IAll airbag system wiring harness and con-
nectors are yellow. Do not use electrical test
equipment on these circuits.
IBe careful not to damage airbag system wir-
ing harness when servicing the cruise control
module and cruise control command switch.
B: PRE-INSPECTION
1. FUNCTION TESTS
Conduct road tests by selecting a smooth, flat road
or use free rollers for road test simulation.
ICruise Control Main Switch
1) Turn ignition switch to ON.
2) Check that cruise control main switch indicator
light comes on when main switch is pressed (ON).
3) Check that main switch indicator light goes out
when main switch is pressed again (OFF).
4) Turn ignition switch to OFF with main switch ON
(indicated by illumination). Turn ignition switch ON
again to ensure that main switch indicator light
remains OFF.
ICruise Control Command Switch
1) Check that cruise control command switch is
properly set in ªSET/COASTº, ªRESUME/ACCELº,
or ªCANCELº mode.
2) Also check that command switch returns to the
original position when released.
IConstant Speed Test
1) Turn cruise control main switch to ON.
2) Drive the vehicle at a speed greater than 40
km/h (25 MPH).
3) Press command switch to set in ªSET/COASTº
mode.
4) Ensure that vehicle is maintained at the speed
set when command switch was pressed.
IAcceleration Test
1) Set vehicle speed at a speed greater that 40
km/h (25 MPH).
2) Ensure that vehicle continues to accelerate
while holding command switch in ªRESUME/
ACCELº mode, and that vehicle maintains that
optional speed when command switch is released.
IDeceleration Test
1) Set vehicle speed at an optional speed greater
than 40 km/h (25 MPH).
2) Ensure that vehicle continues to decelerate
while holding command switch in ªSET/COASTº
mode, and that it maintains that optional speed
when command switch is released.
NOTE:
When vehicle speed reaches the lower speed limit
of 30 km/h (19 MPH) during deceleration, cruise
control will be released.
2. CRUISE CONTROL CABLE
3B21 : CHECK CRUISE CONTROL CABLE.
Check accelerator cable (A) and cruise control
cable (B) installation.
S6M0099B
:Is the cruise control cable securely
installed to the left of the accelerator
cable?
: Go to step3B22.
: Install cruise control cable securely. Go
to step3B22.

1. General
A: PRECAUTION
IIf any of the airbag system parts such as
sensors, airbag module, airbag control module and
harness are damaged or deformed, replace with
new genuine parts.
G5M0291
IWhen servicing, be sure to turn the ignition
switch off, disconnect the negative (þ) battery ter-
minal then the positive (+) terminal in advance, and
wait for more than 20 seconds before starting
work.
G5M0292
IWhen checking the system, be sure to use a
digital circuit tester. Use of an analog circuit tester
may cause the airbag to activate erroneously. Do
not directly apply the tester probe to any connec-
tor terminal of the airbag. When checking, use a
test harness.
